Description

Technical Field

[0001] The invention relates to the technical field of cable laying for electric power engineering, and in particular to a construction auxiliary device for cable laying for electric power engineering. Background Art

[0002] Cable laying in power engineering refers to the process of installing and arranging power cables in the power system according to the design requirements. There are several ways to lay power cables: direct burial, pipe laying, shallow trough laying, cable trench laying, etc. Cable trench laying is an installation method in which power cables are laid in a specially excavated cable trench to protect the cables from the influence of the external environment and facilitate maintenance and inspection.

[0003] At present, there are the following disadvantages in laying power engineering cables: 1. When laying power engineering cables, several brackets for supporting cables are usually installed on the side walls of the cable trench first, and then the cables are placed on the brackets one by one. After the entire row of cables are placed on the brackets, the laying of the cables is completed. However, in the above operation process, after the laying is completed, it is necessary to manually organize and divide the cables in the entire row. The manual operation is inefficient, which will lead to delays in the overall construction progress, and manual operation is prone to cable identification errors or improper distribution. The wrongly combed cables are prone to cable interlacing and entanglement, making it difficult to distinguish during subsequent maintenance and repair, thereby increasing the difficulty of subsequent work; 2. After the entire row of cables is laid, each cable is not separated one by one, so that the cables in the entire row will be squeezed against each other, and the squeezing of the cables against each other will cause the outer sheath to wear, increase the risk of cable damage, and affect its service life. In addition, the squeezing of the cables against each other may affect the heat dissipation performance of the cables, and at the same time cause interference between the cables, affecting the signal transmission quality, especially in communication cables, which may cause signal attenuation and interference.

The main body 51 is provided with a driving part 52 that provides power for the wire management mechanism 6 and a docking part 53 that cooperates with the support part 41 to determine the position of the mobile base 1.

[0033] See also Figure 1 and Figure 5 The wire management mechanism 6 includes a wire dividing portion 61 arranged on the main body 51 and used to clamp and straighten both sides of a single cable. The wire dividing portion 61 is provided with a combining portion 62 for adaptively separating each cable and a wire contact portion 63 for rolling contact with the cable.

[0034] See also Figure 1 , Figure 2 , Figure 3 and Figure 4 The support portion 41 includes a triangular support block 411, a limiting sliding hole 412, a limiting slide plate 413, an isolation plate 414 and an alignment block 415. A plurality of triangular support blocks 411 with cavities inside are fixedly installed on the front end surface of the fixed plate 2 in a linear array from top to bottom. A plurality of limiting sliding holes 412 are penetrated through the upper end surface of the triangular support block 411 in a linear array from front to back. A limiting slide plate 413 is slidably installed up and down in the triangular support block 411. An isolation plate 414 corresponding to the limiting sliding holes 412 is fixedly installed on the upper end surface of the limiting slide plate 413. An alignment block 415 with a V-shaped alignment groove is fixedly installed on the front end of the triangular support block 411.

[0035] In the specific work, before laying the cables, first fix a number of fixing plates 2 on the side wall of the cable trench, and then manually or mechanically lay the whole row of cables on the triangular support blocks 411 on the same horizontal plane, so that the triangular support blocks 411 on the same horizontal plane support the whole row of cables. When the whole row of cables is laid on all the triangular support blocks 411 from top to bottom, the laying of the cables is completed.

[0036] See also Figure 1 , Figure 2 , Figure 5 and Figure 6 The main body 51 includes an electric slide rail 511, a support slide 512, a connecting cross plate 513 and a support arm 514. The electric slide rail 511 is fixedly installed on a side wall of the support column 3 close to the fixed plate 2, and the supporting slide 512 is fixedly installed on the movable end of the electric slide rail 511. The rear end surface of the supporting slide 512 is fixedly installed with a connecting cross plate 513 corresponding to the triangular support block 411. The connecting cross plate 513 is fixedly installed on a side wall close to the triangular support block 411 with left-right symmetrical support arms 514, and the triangular support block 411 is located between the corresponding left-right symmetrical support arms 514.

[0037] See also Figure 1 , Figure 2 and Figure 5The docking portion 53 includes a connecting seat 531 and an alignment vertical rod 532. A side wall of the supporting slide 512 close to the fixed plate 2 is hinged with an upper and lower connecting seat 531 through a torsion spring. The upper and lower connecting seats 531 are jointly fixed with an alignment vertical rod 532, and the alignment vertical rod 532 corresponds to the V-shaped alignment groove.

[0038] During the specific operation, after the entire row of cables is laid, the movable base 1 is started to move it with the support column 3 to the position corresponding to the triangular support block 411, and then the movable base 1 is started to move with the support slide 512 through the support column 3 to approach the triangular support block 411. During the approaching process, the alignment vertical rod 532 will enter the alignment block 415. When the alignment vertical rod 532 is pressed into the rear side of the V-shaped alignment groove, the movable base 1 can no longer approach the side wall of the cable trench. In this way, the position of the movable base 1 can be determined according to the triangular support block 411, and the position of the wire management mechanism 6 can be determined at the same time. At this time, the electric slide rail 511 is in an unstarted state, and the left-right symmetrical support arms 514 are located below the left and right sides of the corresponding triangular support block 411, so that the left-right symmetrical support arms 514 will not collide with the current triangular support block 411 when following the movable base 1 to move to the next group of triangular support blocks 411.

[0039] See also Figure 1 , Figure 5 and Figure 6 The driving unit 52 includes a transmission shaft 521 and a first motor 522. The transmission shaft 521 is installed in the support arm 514 through a bearing. The transmission shafts 521 distributed up and down on the same side are connected by a first belt transmission. The transmission shafts 521 located at the bottom and symmetrically are connected by a second belt transmission. A first motor 522 whose output end is fixedly connected to one of the transmission shafts 521 is fixedly installed on the connecting cross plate 513 through a motor seat.

[0040] See also Figure 5 , Figure 7 and Figure 8 The dividing line portion 61 includes a second slideway 611, a bidirectional threaded sleeve 612, a third slider 613 and a clamping block 614. The upper end surface of the support arm 514 is provided with a second slideway 611 corresponding to the limiting sliding hole 412. A bidirectional threaded sleeve 612 is installed in the second slideway 611 through a bearing. The bidirectional threaded sleeve 612 on the same support arm 514 is fixedly connected to the corresponding transmission shaft 521. A third slider 613 is slidably installed in the second slideway 611, and a clamping block 614 is fixedly installed on the upper end of the third slider 613. The side wall of the upper ends of the front-to-back symmetrical clamping blocks 614 in the same second slideway 611 that are close to each other is an inclined surface.

[0041] See also Figure 5 and Figure 8The combination part 62 includes a combination column 621 and a combination hole 622. The rear end face of the clamping block 614 located on the front side is provided with a combination hole 622. The front end face of the clamping block 614 located on the rear side is fixedly installed with a combination column 621 that cooperates with the combination hole 622. The combination column 621 located on the rear clamping block 614 cooperates with the combination hole 622 on the adjacent front clamping block 614.

[0042] See also Figure 5 and Figure 7 The contact wire portion 63 includes a matching groove 631 and a roller 632. A matching groove 631 is provided on one side wall of the front-to-back symmetrical clamping blocks 614 close to each other in the same second slideway 611. A plurality of rollers 632 are rotatably installed in the matching groove 631 from left to right through bearings.

[0043] During specific operation, after the position of the cable management mechanism 6 is determined, the electric slide rail 511 is started to drive the left and right symmetrical support arms 514 to rise to the bottom of the corresponding row of cables through the support slide 512. At this time, the left and right symmetrical support arms 514 are just located on the left and right sides of the corresponding triangular support block 411.

[0044] During the rising process of the support slide 512, the first motor 522 is in an unstarted state, and the combination column 621 located on the rear clamping block 614 will be inserted into the combination hole 622 on the adjacent front clamping block 614, so that the rear clamping block 614 and the adjacent front clamping block 614 form a whole, and the inclined surfaces at the upper ends of the two will form a triangle. Therefore, during the rising process of the support arm 514, the entire row of cables will be separated and guided through the triangle. At this time, under the action of the weight and guidance of the cables themselves, the entire row of cables will be separated, and when the cables contact the upper end surface of the support arm 514, the cable separation operation is completed.

[0045] Then, the first motor 522 is started to rotate with the transmission shaft 521 fixed thereto, and through the transmission of the first belt and the second belt, all the transmission shafts 521 are synchronously rotated, and the rotation of the transmission shaft 521 will rotate the bidirectional threaded sleeve 612, so that the front-to-back symmetrical third sliders 613 in the same second slideway 611 are close to each other, so that the upper clamping block 614 clamps and straightens each cable front and back, and the contact surface between the clamping block 614 and the cable is the roller 632, so that the support arm 514 will not cause friction damage to the cable when moving, so as to synchronously complete the branching and cable management operations of the entire row of cables, thereby enhancing the overall aesthetics and neatness.

[0046] See also Figure 1 , Figure 2 , Figure 3 and Figure 4The isolation portion 42 includes a matching slide groove 421, a first slider 422 and an extrusion block 423. The triangular support block 411 is provided with a matching slide groove 421 that runs through its left and right end surfaces. A first slider 422 located below the corresponding limiting slide plate 413 is slidably installed in the matching slide groove 421. An extrusion block 423 is fixedly installed on the upper end surface of the first slider 422. The upper end surface of the extrusion block 423 is composed of a flat surface on the right and an arc surface on the left. A side wall of the limiting slide plate 413 close to the corresponding extrusion block 423 is chamfered.

[0047] See also Figure 2 , Figure 3 and Figure 4 The locking portion 43 includes a first slide 431, a second slider 432, an insertion rod 433 and a socket 434. The left end surface of the triangular support block 411 is provided with a first slide 431 that is symmetrical front and back about the corresponding matching slide groove 421. The second slider 432 is slidably installed in the first slide 431 through a set spring. The insertion rod 433 is fixedly installed on the second slider 432. The first slider 422 is provided with a socket 434 that cooperates with the insertion rod 433.

[0048] During specific work, after completing the branching and cable management of the entire row of cables, start the movable base 1 to move it a certain distance to the left, and the support arm 514 on the right will contact the first slider 422 and push the first slider 422 to the left, and the extrusion block 423 will squeeze the limiting slide plate 413 upward and lift it up, so that the isolation plate 414 slides out of the limiting slide hole 412, thereby separating and spacing each cable after branching by the cable management mechanism 6, thereby effectively reducing the electromagnetic interference between the cables, ensuring the quality and stability of signal transmission, and enhancing its heat dissipation effect. In this process, the connecting seat 531 will be offset by a certain angle with the alignment vertical rod 532 under the action of the hinge.

[0049] During the movement of the first slider 422, under the action of the spring, the insertion rods 433 on both sides will always be against the front and rear end surfaces of the first slider 422. When the first slider 422 moves a certain distance to the left, the socket 434 will move to the position corresponding to the insertion rod 433, and then under the action of the spring, the insertion rod 433 will be inserted into the socket 434, thereby fixing the first slider 422, thereby locking the position of the limiting slide plate 413, so that the isolation plate 414 will not drop.

[0050] Then, the first motor 522 is started in reverse to return the clamping block 614 to its original position, and the electric slide rail 511 is started in reverse to lower it with the support arm 514 , and then the entire row of cables on the next set of fixed plates 2 can be combed through the mobile base 1 .

[0051] See also Figure 1-Figure 8Working principle: Before laying the cables, first install several fixing plates 2 on the side walls of the cable trench, then manually or mechanically lay the entire row of cables on the triangular support blocks 411 on the same horizontal plane, and then start the mobile base 1 to determine the position of the cable management mechanism 6 through the docking part 53 and the support part 41.

[0052] Then, the electric slide rail 511 is started to drive the left and right symmetrical support arms 514 to rise to the bottom of the corresponding row of cables. During this process, the entire row of cables will be guided for branching, so as to perform branching operations on the entire row of cables. Subsequently, the first motor 522 is started to clamp and straighten each cable front and back, so as to synchronously complete the branching and cable management operations of the entire row of cables.

[0053] Then, the movable base 1 is started to move it a certain distance to the left, and each cable after branching by the cable management mechanism 6 is separated and spaced through the isolation part 42, and the locking part 43 locks the position of the limiting slide plate 413. Then, the first motor 522 is started in reverse to make the clamping block 614 return to its original position, and the electric slide rail 511 is started in reverse to make it descend with the support arm 514, and then the entire row of cables on the next group of fixed plates 2 can be combed through the movable base 1.
